    A novel loop catheter technique simplifies left adrenal vein catheterization, a crucial procedure for hypertension evaluation. This method proved quick and effective in 33 patients, facilitating adrenal venography.

    Area of Science:

    • Interventional Radiology
    • Vascular Access Techniques
    • Endocrinology

    Background:

    • Hypertension diagnosis often requires adrenal vein sampling to identify underlying causes.
    • Accurate catheterization of the left adrenal vein is technically challenging.
    • Minimally invasive techniques are sought to improve procedural efficiency and patient outcomes.

    Purpose of the Study:

    • To describe a simple and effective loop catheter technique for left adrenal vein catheterization.
    • To evaluate the feasibility and efficiency of this technique in patients undergoing hypertension workup.

    Main Methods:

    • A loop catheter technique was employed for selective left adrenal vein catheterization.
    • The procedure was performed on 33 patients evaluated for hypertension.

  • Procedure time and success rate for catheter placement were recorded.
  • Adrenal venography was performed in a subset of patients (n=14).

    • Main Results:

    • Selective catheter placement into the left adrenal vein was achieved in all patients.
    • The average time for successful catheter placement was 3-5 minutes.
    • The loop catheter technique demonstrated high efficiency and technical success.

    Conclusions:

    • The loop catheter technique provides a simple, rapid, and effective method for left adrenal vein catheterization.
    • This technique is suitable for patients undergoing evaluation for hypertension.
    • It facilitates subsequent diagnostic procedures like adrenal venography.
